/**
 * @file hltout-collect-esd.C
 * @brief Example for the AliHLTEsdCollectorComponent
 *
 * Example macro to run a small chain with the AliHLTOUTPublisherComponent
 * and the AliHLTEsdCollectorComponent. The AliHLTOUTPublisherComponent
 * is configured to publish all ESD objects from the HLTOUT data, the
 * AliHLTEsdCollectorComponent writes the files using the AliHLTEsdManager.
 *
 * Usage: aliroot -b -q hltout-collect-esd.C | tee hltout-collect-esd.log
 *
 * The macro asumes HLTOUT raw data ddl files in order to open an
 * AliRawReaderFile, e.g. simulated using the default AliSimulation with
 * at least SetWriteRawData("HLT") enabled.
 *
 * \b Note: The example disables a few steps in the AliReconstruction,
 * mainly because of crashes in various parts of AliRoot. This does not
 * have any impact to the HLT features to be presented.
